3 Series

Planetary Gear Units

Bonfiglioli's 300M Series is an outstanding solution for all heavy-duty applications where compactness is not an option.Thanks to its modular design, the 300M Series can be customized to match an extremely wide range of applications. Bonfiglioli's expertise in planetary technology ensures high-quality product design and manufacturing procedures. The 300 Series operates without unwanted downtime even in the harshest environments. This planetary gearbox achieves top-class flexibility thanks to several outputs, as well as input configurations available for all 20 sizes. The 300M Series can be completed with a wide range of electric motors entirely manufactured by Bonfiglioli. Asynchronous motors (BN-BE-BX/M-ME-MX) can be coupled with 300M Series gearboxes, providing our customers a complete solution. Read less...
